Unpacking Open carton and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Lever Hoist is assembled and running properly. Read this entire instruction manual thoroughly for set-up, maintenance and safety instructions. Contents of the Carton 1 1 1 Lever Hoist Owner's Manual Warranty Card Installation Support for the hoist may be hook, clevis pin, trolley, or beam clamp.
The load chain supplied with your JET lever hoist is designed, manufactured, and tested for proper fit and durability. If chain should ever need replacing, for your own safety use factory replacement chain only. Use of other than factory replacement chain may cause serious injury and/or damage to the lever hoist. Never extend load chain by welding a second piece to the original. Inspecting Hooks It is important to check top and bottom hooks for proper opening and other signs of deformation or damage.
Operation The JLH Lever Hoist may be used either in vertical position as a hoist; or in angled or horizontal position as a puller. Below is the general procedure for operating the hoist: 1. Set the top hook securely. 2. Place the selector switch on the handle in the center neutral position, and pull out on the handwheel (A, Figure 4). This will allow “freewheel” mode. Pull the load chain by hand to position the bottom hook. 3. Correctly center the load on the bottom hook (Figure 5).
• Prevent the chain from dragging over sharp edges or corners. This will cause links to weaken, bend, or break. • When connecting to a wire rope sling, the lever hoist must be applied along a straight line parallel to the surface on which it is resting. See Figure 7. • When lifting loads, hook the load with slings. Do not use the lever hoist chain as a sling (Figure 8). • Both ends of a sling or rope must be completely on the inside of the safety latch before pulling or lifting the load.
Allowable Limits for Load Chain and Hooks Load Chain Carefully inspect the entire load chain. As illustrated in Figure 9, measure five consecutive links with calipers to find the length, Compare the results with the table in Figure 9. Check every three feet and especially where excessive wear is indicated. Any load chain that shows noticeable deformation or heat influence must be replaced with a new one. Never extend load chain by welding a second piece to the original.
Timing Marks for Gear Replacement If the gears on the JLH hoist need replacement or removal for any reason, make sure they are re-installed correctly. Figure 12 shows the proper orientation of the timing marks when meshing the gears. Figure 12 Troubleshooting The numbers in parentheses refer to the parts breakdown on the following page. Trouble Probable Cause Remedy* Hoist will not lift (no clicking sound). Pawl (#12) not engaging ratchet disc (#15); possible dirt or foreign material.
